Mercedes-Benz CLS Suspension Leg Replacement Parts

A suspension leg (also called a MacPherson strut) combines the shock absorber and the top spring mount into a single unit, and yes, the CLS does use this design at the front axle across all generations. The rear suspension uses a multi-link arrangement rather than struts, so if you need a rear suspension component you will be looking for something different such as a shock absorber or trailing arm. When searching, make sure you specify front, as 'suspension leg' on the CLS refers to the front nearside or offside strut assembly.

The CLS was built across two main generations: the first-generation W219 ran from 2004 to 2010, and the second-generation W218 ran from 2011 to 2018. These two generations have completely different front subframe and suspension geometry, so parts from a W219 will not fit a W218 and vice versa. Always confirm the generation of the donor car with the breaker before purchasing, and give them your registration to cross-reference.

On the CLS, engine size can influence front suspension components because heavier or more powerful engines may use uprated spring and damper rates or different strut specifications. The basic strut assembly is broadly similar across the range, but differences between, say, a 220d four-cylinder and a 500 V8 are plausible enough that you should confirm the exact engine variant of the donor car matches yours when speaking to the breaker. Do not assume a leg from a smaller-engined car will be a straight swap onto a V8 model without checking.

The CLS was available in trim levels including SE, Sport, and full AMG variants, and trim level alone does not change the fundamental strut design. However, AMG models and cars fitted with the optional sports or lowered suspension may use different spring rates or damper settings compared to standard cars, so you should confirm with the breaker whether the donor car had standard or sport suspension before buying. The physical fitment side (NS or OS) absolutely does matter, so always specify nearside or offside when ordering.

The W218 received a facelift in 2014, and while the front suspension architecture remained the same platform throughout the W218 generation, whether specific strut components interchange across the 2014 facelift boundary is something you should confirm with the breaker against your registration number. It is quite possible they are the same part, but mid-generation running-gear revisions do occur and cannot be ruled out without checking. Give the breaker both your reg and the donor vehicle's reg so they can verify the parts match.

Yes, side absolutely matters — a nearside (NS, left-hand side from the driver's perspective) suspension leg is not interchangeable with an offside (OS, right-hand side) leg because the strut geometry and top mount orientation are handed. Always tell the breaker clearly whether you need the NS or OS unit, and double-check this against your own car before ordering. Buying the wrong side is one of the most common and easily avoided mistakes with suspension parts.
